CHARLES H. HOlVLAND-SHERMAN AND ALAN M. BENNETT, OF WASHING TON, DISTRICT OF COLUMBIA, ASSIGNORS OF THREE-FOURTHS TO AGNES S. ADAM, OF SAME PLACE.

PEA-SHELLER.

SPECIFICATION forming part of Letters Patent No. 666,312, dated January 22, 1901.

Application filed February 19, 1900. Serial No. 5,724. (No model.)

T at whom, it may concern.

Be it known that we, CHARLES H. HOW- LAND-SHERMAN and ALAN M. BENNETT, citizens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Pea-Shellers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to pea-shellers, has for its object the production of a simple, efficient, and inexpensive article, and consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accoi'npanying drawings, which form part of this specification, Figure 1 represents a front elevation of our pea-sheller; Fig. 2, a side elevation of the same; Fig. 3, a vertical transverse section on the line 3 3, Fig. 1; Fig. 4, a rear elevation showing the compression of the enlarged ends of the cylinders; Fig. 5,

a vertical section of the front of the machine on line 5 5, Fig. 6; Fig. 6, a rear elevation of the front of the machine detached and showing the inside thereof, and Fig. 7 a longitudinal section of one of the cylinders detached 0 and showing the shaft in side elevation. I

Reference being had to the drawings and the letters thereon, A indicates the body or frame of the machine, and B the detachable front, having inwardly-extended flanges Ct at on the 5 ends thereof, which are provided with elongated and preferably rectangularbearings b 1),

open on one side for the shafts c of the cylinders d, and to avoid the expense of turning the customary collars 011 each end of the cylinders as a lateral bearing to clear the bodies of the cylinders from the frame or of inserting washers for the same purpose the cylinders are cut off square preferably from round merchantable wood-stock, and lateral projections 6 e on the inside of the flanges are substituted for said collars, being cast thereon in such position as to prevent excessive longitudinal play of the cylinders in the same manner as it would be prevented by collars 0r Washers. The bearings 12 Z) for the shafts of the cylinders 01 are cast in the flanges to avoid the necessity of drilling, boring, or otherwise machining the bearings and facilitate the assembling of the cylinders with the body A and the detachable front, as the rolls are simply placed in the front B, with the shafts d lying in the bearings b b, and the front secured to the body by screws 9. The bearings as constructed reduce the superficial friction of the shaft to a minimum, the ob- 6o ject being to avoid the cost of drilling bearings in the body or the flanges and driving the shafts through the cylinders in assemblingin the usual manner and to afford ready means for renewing the cylinders of the machine. The front 13 is also provided with a mouthpiece 0, closed on its upper side and having, primarily, the function of receiving the peas as fed to the rolls or cylinders and, secondarily, combining with that function the guidance out of the sheller of the peas as they are shelled. This mouthpiece is inclined downward and outward to prevent peas as they are expelled from the pod being projected away from the receptacle designed to 001- lect them. The mouthpiece crosses the machine longitudinally and is provided with a rectangular openingfto simultaneously admit several pods abreast as they are fed to the machine by the hand of the operator, and the upper side of the mouthpiece deflects the peas downward as they are discharged.

The front is secured to the body of the machine by screws g, which pass through the sides h h and engage the hOlQSiilIl the flanges a a, as shown in Figs. 2, 4, and 6.

The cylinders 11 are preferably made of wood and provided with a covering it on the shelling part thereof and an enlarged covering Z Z at the ends, the central portion presenting a plain surface and the ends preferably a corrugated surface, with the corrugations of one cylinder meshing into the corrugations on the other cylinder under a degree of compression to produce an effective mesh, bite, or friction to cause the cylinders to be revolved synchronously, and whereby the parallelism, equal yield, and continuous engagement of the rolls are maintained. These coverings are all of a resilient material, such :00

as rubber, being preferably made of inerchantahle tubingplain and corrugated out into proper lengths and cemented to the wooden cylinders, and the cylinders are held in proper relation to each other, with the enlarged ends compressed and the central portions preferably just in engagement or slightly separated by the shafts c of the cylinders engaging the outer ends of the elongated bearings Z) Z) in the flanges a a of the front B, as shown in Fig. 2.

One of the shafts c is provided with a crank '11, by which the cylinders d are revolved to shell peas as they are supplied to the machine, and the machine is provided with a bracket 0, having a jaw p and a thumb-screw g, by which it is secured to a table or other suitable support.

In the operation of the machine peas fed through the mouthpiece O are caught between the central parts of the cylinders d, the air in the pods compressed, the pods burst, and the peas expelled from the pod and discharged through the mouthpiece, while the pod travels on through between the cylinders and is discharged at the rear open and unobstructed end 0 of the machine.

The open and unobstructed rear end of the machine affords ready access to the cylinders and also affords ready inspection thereof to ascertain their condition.

The coverings of the cylinders (1 may be readily renewed at a Very slight expense when they become worn, as the rubber tubing of which they are made may be found for sale in any well-equipped store dealing in rubber goods.

Having thus fully described our invention, what we claim is 1. In a pea-sheller, the combination of two cylinders, each enlarged at both ends and each having its enlarged end fluted or corrugated; the said rolls being normally held with their ends in compressed relation, whereby the parallelism, equal yield and continuous engagement of the rolls are maintained.

2. A pea-sheller provided with cylinders having resilient surfaces enlarged at their ends, in combination with a frame and adetaehable front having side flanges provided with bearings for supporting said cylinders with theirends in compressed relation to each other, and a feeding and discharge mouthpiece crossing the sheller longitudinally.

3. A pea-sheller provided with cylinders having resilientsurfaces in combination with a frame, and a detachable front having end flanges provided with bearings open on one side for the shafts of the cylinders.

4. A pea-sheller provided with cylinders having resilient surfaces, enlarged at their ends; in combination with a frame, and ade tachable front having end flanges provided with bearings open on one side for the shafts of the cylinders.

53. A pea-sheller provided with cylinders having resilient surfaces, enlarged at their ends; in combination with a frame, anda detachable front having end flanges provided with bearings for the shafts of the cylinders constructed to support the cylinders and secure said ends of the cylinders in compressed relation to each other.

6. A pea-sheller provided with cylinders having resilient surfaces; in combination with a frame, and a detachable front having end flanges provided with bearings open on one side for the shafts of the cylinders and lateral projections 011 the inside of said flanges.

In testimony whereof we afflx out signatures in presence of two witnesses.
